I'm involved in an ongoing debate with an anti-gun friend of mine. Looking for links to info debunking the claim that Mass Murders are on the rise. I know I've read Masaad Ayoob showing mass murders from the 1800's and I'm pretty sure I've seen a time line somewhere showing that in fact there HASN'T been an increase in mass murder incidents. Hoping someone here has some good intel. Thanks in advance.
